The First Ever Emulator You Remenber

[JetPackAndButlers]

VisualBoyAdvance on not so good ol Windows Vista
ZSNES is 2nd to that and i'll never not be impressed at how good that thing was optimized (also the interface is beyond iconic)

VisualBoyAdvance was the first emulator I've seen because I friend gave me a copy. My searching led me to have my first emulator on my own, ZNES; both were when I was using Windows XP.

ZSNES and Chrono Trigger. That was my first incursion ever in emulating, and it was not even my home nor my PC. 1998 if I recall correctly :D
